The Reliability, Availability, and Maintainability analysis makes it possible to forecast, for a given period, the availability and deferred production factor of a production process, based on the system configuration, the reliability of its components, and their operation and maintenance philosophy.

The fundamental basis of this analysis is the determination, through probabilistic or analytical methods, of the Mean Time Between Failures (MTBF) and the Mean Time To Repair (MTTR) of the equipment that makes up the systems, with the purpose of determining their weaknesses and enabling decisions regarding maintenance and reliability policies, inventory management, the use of new technologies, and operational philosophies, both during the design stage and during the normal operation of the facilities.
